I have the class X. I want to destruct it when user click [_] [x]-here (close window button). What should I do? I need it, because I mmap something in class X and I need to munmap it while exit.

Example:

X *myclass;

int main(int argc, char** argv) {
myclass = new X();

//...
// Some glut stuff..
//...

glutMainLoop();

return 1;
}

How to delete myclass or destruct it (myclass->~X) while exit? Where?

P.S.

I use GLUT thread and create new window with GLUT too. TNX!

Try the atexit() function.


#include <stdlib.h>

void myAtExit()
{
// destroy stuff ...
}

int main(...)
{
...
atexit( myAtExit );
glutMainLoop();
return 0;
}
edit:

I see that this has been answered in another forum.
